Conservation Grade trees are plants that are healthy but do not fit the shape standards for our normal nursery stock sales. Typically trees have crooked stems and irregular or few lower branches that prevent the trees from having immediate ornamental value. However the root structure is good and these trees grow just as well as our standard crop of straight/upright seedlings but at a 50% discount. Conservation Grade trees are popular as a source for cheap trees to be used in large landscape plantings where immediate ornamental appeal is not necessary. As trees grow they will develop the correct structure and a mature Conservation Grade tree will be indistinguishable from a standard Nursery Grade tree. Staking seedlings is usually a good idea to ensure the stems will straighten up.The Giant Coastal Redwood is one of the most unique and amazing trees in the world, and has become very popular in cultivation worldwide. Although the species grows in a very limited range naturally, it grows in a very large number of conditions and survives in most environments as long as summer water is available. However, these trees are actually far more drought resistant than most people think. At our nursery in Medford, Oregon where average rainfall is about 19 inches with less than 3 of those occurring between June and September (when the average high is in the 90's with 100+ degrees being common, all with very low humidity (10-20% is the most common) we grow Coast Redwoods in the full sun with them being watered only twice each summer. Any landscape with summer watering will have enough moisture to grow this tree. Additionally, there are no major pests or diseases that might attack your tree and make it look sick and yellow. They are also more cold tolerant than most people think - our trees survived -5 degrees for two days straight without even leaf damage.
One of the most interesting aspects of the Coast Redwood is its generation ability. In general, conifers can produce new growth only from existing buds - branches that are cut off will leave a permanently bare trunk, trees cut to the ground will yield a dead stump. Redwoods can produce new buds from old growth along the trunk or from the stump, which has actually been useful to us for maintaining low branching. Because other conifers can't regenerate low branches, pruning them causes dead spots on hedges. This is very true for Arborvitae, which deer tend to eat during the winter. In hard years they eat all the bottom branches, leaving a permanently bare trunk. We love using Redwoods for hedges because they can be continually topped and pruned and will stay dense and full. Additionally, the roots can regenerate and will handle disturbance such as digging or being buried deeper far better than most other trees. In the wild they are well adapted to growing in flood plains where rivers can deposit large amounts of silt over their roots.
Coast Redwoods are known for their incredible shade tolerance, and will grow straight and fast even in deep shade. They are one of our favorite conifers and is the first conifer we started propagating (again unlike many other conifers, Coast Redwoods can be propagated by stem cuttings). When given space and time, they will grow quite large, but they can also be pruned to a hedge or even kept as a bonsai. However, because of their fast growth and immense potential size, we don't recommend planting these in tight residential settings near buildings or property borders.
The Giant Coastal Redwood is the world's tallest tree, with some of the tallest growing to more than 300 feet high with trunks 30 feet in diameter! Redwoods are famous for their fast growth of up to seven or eight feet per year, massive sizes, and incredibly rot resistant wood. The tree's heartwood takes on a red color over time as decay resistant chemicals accumulate in the wood, which is fairly light and even grained. The wood is very strong and the huge demand for the incredible wood has left only very small populations of Redwoods unlogged. The species now only occupies a few percent of its original range and has been listed as an endangered tree. Luckily, a mature tree can produce 5-8 million seeds per year and although the seeds tend to have low viability, plenty of seedlings can be grown each year for reforestation.
